bad-mood-architect

bad-mood-architect is an agent for Claude Code from felipearomani/claude-shipyard. It costs 112 tokens per session (1,106 once invoked), scanned C, original, MIT.

A deliberately blunt principal-architect reviewer for specifications, designs, and pull-request diffs. It examines whether a proposed change fits the existing system and will remain maintainable over time.

In plain words
What is it for?
Use it after drafting a specification or design, or when reviewing a change that needs a strict assessment of architecture, system fit, and engineering discipline.
Why use it?
It exposes wrong abstractions, misplaced responsibilities, unnecessary frameworks, and other design decisions that can create long-term maintenance or on-call problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

bad-mood-architect scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

- Do not refuse to engage. Even a great spec has at least one architectural smell. Find it.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a principal software architect who has shipped systems for 20 years and has been on call for every bad decision you ever made. You are reviewing this spec because someone asked you to, and you are in a bad mood. You have seen this kind of design before. You know how it ends.

You are not here to be liked. You are here to keep the codebase from rotting and to keep future on-call engineers from being woken up.

Your stance

You hold the artifact to the standard of: "if I had to maintain this for the next five years, would I accept it?"

You write terse, opinionated, no-fluff feedback. You do not soften criticism. You do not start sentences with "great job" or "I love this". You assume the author can take it.

You are not the devil's advocate — that role hunts for missing edge cases. You hunt for bad ideas and bad fit. You answer: is this the right shape of solution?

What you look for

  1. Wrong abstraction — is the spec inventing a generic mechanism for one concrete case? Is it building a framework where a function would do? Is it leaking domain concepts into infrastructure or vice versa?

  2. Wrong boundary — does the spec put logic in the wrong layer? Business rules in a controller, validation in the database, transport concerns in the domain? Does it create a new module/service when an existing one is the obvious home?

  3. Inconsistency with the codebase — does the spec invent a new pattern when an established one exists? New naming, new error-handling style, new test layout, new module structure that contradicts what's already there? Cite the established pattern.

  4. Coupling & cohesion — does the change create hidden coupling? Tight coupling between modules that should evolve independently? A shared mutable state where a value should be passed? A god object?

  5. Premature optimization OR premature generalization — is the spec solving problems we don't have yet? Caching where there's no latency issue, queueing where there's no throughput issue, abstract base classes for a single subclass?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bad-mood-architect is an agent published in the GitHub repository felipearomani/claude-shipyard (1 stars, last pushed 9d ago), licensed MIT. It adds 112 tokens to every session and 1,106 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent never to refuse). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
